Reduced Blood Pressure and Lower Stress Levels: Alan Beck, Ph.D., director of the Center for the Human-Animal Bond at Purdue University School of Veterinary Medicine and his co-researcher Aaron Katcher found in the early '80s that when people interact with dogs, "you actually get a drop in blood pressure -- a true relaxation response," he says. More recently, researchers in Japan found that dog owners who were bonded to their pets experienced a spike in oxytocin -- a neurotransmitter that helps us cope with stress -- from simply meeting their dogs' gazes.
We're social animals, so we gravitate toward this kind of bonding behavior: "Every culture has touch as a positive thing, because social animals have to be near each other," Beck says. Feeling a bit stressed? Try taking a few moments to pet or cuddle with your pup. He'll benefit from it, too.
A Healthier Mind: "The greatest pleasure of a dog is that you may make a fool of yourself with him, and not only will he not scold you, but he will make a fool of himself, too," Samuel Butler, the novelist, once said. As we age, it's so easy to get caught up in our work and our daily list of "to do's" that we forget how to play. If you let him, your dog can be a portal into a more visceral, imaginative, emotional world -- and a less self-conscious one.
In a recent episode of NPR's Fresh Air, Jonah Lehrer points out that in fourth grade, kids start to become aware of the possibility of making mistakes, which can hugely limit their artistic creativity. "All of a sudden, they're aware that you can draw the wrong line, you can put the brush in the wrong place," he says. Being foolish with our dogs can -- momentarily and hopefully beyond -- push us out of this state of self-reproach.
